試著使用PHP 8架設環境時，遇到相依性套件僅支援PHP 7.x版的問題。
$ composer install --no-dev
Installing dependencies from lock file
Verifying lock file contents can be installed on current platform.
Your lock file does not contain a compatible set of packages. Please run composer update.
Problem 1
- illuminate/container is locked to version v5.8.36 and an update of this package was not requested.
- illuminate/container v5.8.36 requires php ^7.1.3 -> your php version (8.0.3) does not satisfy that requirement.
Problem 2
- illuminate/contracts is locked to version v5.8.36 and an update of this package was not requested.
- illuminate/contracts v5.8.36 requires php ^7.1.3 -> your php version (8.0.3) does not satisfy that requirement.
查了一下發現Composer 2有加入--ignore-platform-req的參數，提供忽略PHP版差和ext-相關套件。
# 忽略PHP版差
composer install --ignore-platform-req=php
# 忽略ext-zip
composer install --ignore-platform-req=ext-zip
